9 Person Instant Cabin Tent
Skip until brand discloses waterproof coating chemistry.
Core Equipment does not disclose the water-repellent coating used on this tent fabric. Instant cabin tents commonly use PFAS-based water repellents; without verification, PFAS risk cannot be ruled out.

What 9 Person Instant Cabin Tent is made of, ingredients and materials
This tent is constructed from polyester fabric with an applied water-repellent coating. Polyester itself is a stable synthetic polymer with low leaching risk under normal use. The water-repellent coating is the chemical wild card, Core Equipment has not disclosed whether it contains PFAS (fluorinated compounds that shed into soil and water) or alternative durable water repellents. Without transparency, you cannot know the persistence and environmental fate of the finish.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Antimony in polyester
Antimony trioxide is a common catalyst in polyester fiber production. It is not typically a leaching hazard during normal tent use because it is bound into the polymer matrix, but degraded or incinerated polyester can mobilize it. No specific testing data for Core tents is available.
Water-repellent coating degradation and leachate
All water-repellent coating finishes, whether fluorinated or non-fluorinated, degrade over time with UV and weathering. Reapplication or re-coating is common. Undisclosed coating chemistry means you cannot predict what degradation products may shed into groundwater or soil during the tent's life and after disposal.
What’s reassuring
Formaldehyde / VOCs
Polyester does not require formaldehyde-based finishing resins. No formaldehyde-containing treatments are standard in water-repellent coatings for this category; risk is not on record for Core tents.
Source, ATSDR ↗Azo dyes
No specific information on dye chemistry for this tent fabric. Polyester textiles can be dyed with azo or non-azo colorants; Core does not disclose dye class. Risk is not established but also not ruled out without testing.
Flame retardants
Recreational tents are not required to meet flammability standards in the U.S. and typically do not carry added flame retardants. Core does not market flame resistance; none is on record.

The brand's record and disclosure
Core Equipment has made no public statement about coating chemistry, waterproofing standards (water-repellent coating certification, finish durability testing), or PFAS avoidance commitments. No major recalls or safety controversies are on record for this model. The silence on chemical composition is the primary red flag; responsible tent makers increasingly publish finish specifications and phase-out timelines for legacy fluorinated water-repellent coating.
How it compares in its category
Mid-range recreational tents routinely use fluorinated water-repellent coating finishes because they are durable and cost-effective. Premium and eco-conscious brands (including REI Co-op, Big Agnes, and Nemo) now offer polyester tents with wax-based, paraffin, or other non-fluorinated water repellents. This tent offers no performance or material advantage over alternatives with disclosed coatings; the lack of transparency is a genuine differentiator in the wrong direction.
If you buy it
Store it dry and well-ventilated to prevent mildew; do not machine wash or dry-clean, as solvents and heat degrade the coating and may mobilize finish chemicals. Inspect seams and patches annually; re-coat with a compatible product (ask Core for guidance, though they may not respond) rather than use proprietary sealants of unknown chemistry. At end of life, do not landfill if possible; contact Core or local waste management about textile recycling to limit coating leachate to soil. Assume a lifespan of 5-10 years depending on UV exposure and storage conditions.
